I understand that the wide range of devices LE is running on is challenging to support. The Wife Acceptance Factor of the current state is too low ("lets just use the tablet") and there is no solution in sight, so I switched to Linuxmint Xfce with Kodi in autostart - it gets the job done.
Thank you for your effort trying to solve the problem.
So, back again - sometimes life prioritizes other things than your home cinema...
mglae I tried 11.0-nightly-20230911-0722cfe with pcie_aspm=off. Verified the parameter in dmesg, it reads PCIe ASPM is disabled.
| Boot | Success | Fail |
| Cold | 6 | 3 |
| Warm | 6 | 5 |
Slightly better, but I would consider that not statistically relevant.
Da Flex Then I installed Ubuntu 22.04.3 LTS (Kernel 6.2) and did 20 boots. Wow that is slow compared to libreelec, now I appreciate the just-enough-os even more. After 10 successful warm boots, I switched to shutting it down and doing cold boots, to get some into the statistics.
| Boot | Success | Fail |
| Cold | 10 | 0 |
| Warm | 10 | 0 |
Da Flex I am a bit unsure how to interpret your instructions. When it fails to boot, sshd is not running (see the journal logs). And does the loglevel setting affect some component before Kodi is loaded? The boot process stalls way before Kodi is launched.
As requested, I updated to LibreELEC-Generic.x86_64-12.0-nightly-20230925-49b4b86. The boot statistics match very closely with 11 nightly. By the way, this is not copy-paste, just the summary is exactly the same as 11 nightly boot, in the details you see the slight differences.

And another 20 boots, but with released 11.0.3 for comparison:

I did 20 boots - and can't really spot a difference between warm and cold. But it definitely got kind of better with the nightly:

Thanks for looking into this.
Installed LibreELEC-Generic.x86_64-11.0-nightly-20230911-0722cfe, now the journal is a lot more talkative 
But I had to attach it here as it seems to be too large for ix.io (2MB)
Boot failures still happening as before, but it feels like there are more successful boots now, maybe 3 out of 10 tries.
Upgraded via fresh install from perfectly stable LE9 to LE11.0.3 due to a core add-on no longer functional.
LE11 does not boot reliably:
Legacy image shows same behavior.
I already swapped quiet for debug in syslinux.cfg.
Countermeasures tried until now:
journalctl > http://ix.io/4GUT there you see a few failed boots and a successful one in the end
Similar symptoms:
Both issues do not happen on 11.0.1, but that did not change anything for me.
